2010-Jan-12 UPDATE Jean-Pierre Charras <jean-pierre.charras@gipsa-lab.inpg.fr>
================================================================================
++All
Use wxAutoBufferedPaintDC in OnPaint event
Seems solves slow grid redraw on some PC (tested under Window 7)
and is faster than use wxPaintDC, not buffered
(note MACOSX has natively a double buffer, so no change for MACOSX)
